My Dear Sir. —Thanks for your card and slips of New York 
papers duly received. Since first arrival of Ontario with cattle, 
others have arrived in Liverpool, and I have examined the lungs 
said by Privy Council Inspectors to have pleuro-pneumonia, and 
satisfied all who have seen them that no pleuro-pneumonia has 
arrived here from America; indeed, everybody is surprised that 
such a gross mistake should have been made. The last lot— 
seven in number—examined by me had bronchitis, with collapse 
of the lung, but not a trace of pleurisy nor of pneumonia, yet 
they were declared by the authorities in London to have typical 
pleuro-pneumonia. I have the specimens most carefully pre¬ 
served and am ready to show them to the whole world, and his 
wife, if necessary. 
I should think that the lung-disease at Blissville is something 
very different from pleuro-pneumonia, as it is stated in the re¬ 
port you sent me that “ the diaphragm was covered with exten¬ 
sive congestive spots,” a state of that membrane not known to be 
associated with pleuro-pneumonia constituted as it is here. I 
shall be very glad to learn all about the matter, as it is of pre¬ 
sent importance, not only to America, but to this country, that 
there should be an untrammeled trade in stock. 
Accept my best thanks for your kindness upon this and many 
other occasions. With kind regards, yours faithfully, 
W. W. Willi AMS.
